Pests don't pick dirty homes. They pick reachable ones. Getting ahead of it isn't overreacting. One PestRx plug-in per room makes your home the harder target for rodents, roaches, spiders, and ants. The ones inside head out. The next ones settle somewhere else. No poison, no sprays, no traps near your kids or pets. Backed by our 30-day money-back guarantee.
One sighting is rarely the only kind you'll deal with. Rodents, roaches, spiders, and ants all work the same way: if your home is reachable, more follow. Handling them one product at a time is why the cabinet fills up and the problem never does.
PestRx works at both ends. The pests already inside start leaving, and new ones find your home harder to settle into than the yard next door, so they never move in.
The pests already inside pick up PestRx's ultrasonic field through the floors, walls, and baseboards they travel along. The space stops feeling safe to them. Over the first days, they begin clearing out. No bait. No spray. No bodies to clean up.
The same ultrasonic field also keeps new pests from moving in, and it works the same way on all four. Rodents, roaches, spiders, and ants all take the path of least resistance, so they go where it's easy. PestRx makes your home the harder choice, so it doesn't get picked as a place to nest or feed. It runs at 25,000–65,000 Hz, above anything your household can hear.
Here's the honest version. Pests adapt. Give them one steady tone and within a week or two they treat it like a refrigerator hum and stop reacting. That's why the $15 to $30 fixed-frequency devices quit. PestRx varies its pattern instead of holding one note, which helps it keep working longer. It stays above the hearing range of humans, dogs, and cats, so your household doesn't hear it.
One per floor covers most homes. Nothing to assemble or set up.
All three layers begin the moment you plug it in. You won't hear a thing.
The pests inside head out, and new ones passing through pick somewhere easier instead of your home.

Every review is from a verified purchase. These aren't generic. They're the exact words of people who found the mouse in the garage, the roaches by the sink, the spiders in the corners, and wanted one device for all of it, without chemicals their kids could touch.
We don't curate which reviews appear below. The rating breakdown reflects every purchase, including the ones that weren't 5 stars.
"the ants came in under the sliding door every spring. no way was i putting down borax bait w/ a 4 yr old and two cats on the floor all day. Got PestRx Thursday, plugged them in. by Saturday morning the line of ants along the baseboard was just gone?? thats been 6 months now still nothing"
"Old farmhouse, been dealing w/ carpenter ants every single spring for 11 years. gave up on TERRO stations ages ago. dog kept licking the bait holders. tried PestRx last march w/ 10 units between house + garage. Best spring weve had period. Saw a handful scattering around the first few days, then nothing by day 11. my wife thinks its witchcraft"
"husband is a skeptic about literally everything. called this "pseudoscience". day 11 after i plugged them in, no more mice droppings in his garage workshop where hed been finding them on the bench every week for 2 yrs. he asked me to order another 5-pack for the barn lol. vindication"
"every few months a roach or two would show up in the same kitchen corner at night and we just...deal w/ it. tried the gel baits, ortho spray, the foggers, all of it. they always come back. plugged in 5 PestRx units in april and by day 9 we stopped seeing them when we flipped the light on?? still nothing 6 mos later. husband didnt believe me at first lol"
"found a LINE of ants under the sink TWO NIGHTS before thanksgiving. absolutely was not having an exterminator spray chemicals all over my kitchen 2 days before hosting my in-laws. ordered the 5-pack overnight shipping, plugged em in everywhere. trail was gone by morning. dinner went fine. still a little pissed abt the pandemonium that night tho"
"apartment building in chicago, ground floor unit. the unit next to mine had a roach problem and they started coming right under our shared wall. exterminator quoted me $399 for the first visit ALONE, ridiculous. got 3 PestRx units instead. stopped seeing roaches in my kitchen by day 11. still plugged in 9 months later, nothing"
"we bought our first house last spring and honestly have no idea what's normal. found a trail of ants coming in under the garage door and fully panicked, posted in our neighborhood fb group and 3 separate ppl recommended HelloPest. ordered the 3 pack that night. garage trail broken by day 10. bonus, the spiders we kept finding in the basement corners thinned out too. nothing in the 2 months since. first time homeowner approved ✅"
"tbh this took longer than i expected and stressful because i actually saw MORE spiders the first few days (turns out they get flushed out of hiding + moving around), i almost returned it. by day 11 the bathroom was completely clear, not a single web. the 30 day return window is the only reason i didnt bail early, would never have lasted otherwise. 4 stars not 5 because the waiting was rough."
"after last springs ant invasion in the kitchen (traumatic) i ordered PestRx in february this yr. plugged in 5 units all over. april came and went and we havent seen a single ant since. first time in the 8 yrs weve lived here. husband was the one who reminded me to order again next feb lol"
"wife insisted. i thought it was pseudoscience. then i stopped finding mouse droppings and chewed up rags in my tool drawer in the garage. 10 days in, problem gone. shes never gonna let me hear the end of it but fine, it works."
"im 7 months pregnant and found a trail of ants in the PANTRY of all places. my OB said absolutely no ant bait or sprays anywhere near food prep, rightly so. this was literally the only option that felt safe to me. a couple weeks in and the pantry has stayed clean. my OB actually asked me what i used 😂"
"detached garage, i keep my classic Corvette there. found a mouse nest UNDER THE HOOD last fall, theyd built it right on top of the engine and chewed some wiring, apparently super common with older cars that sit. plugged in 2 units in the garage. havent seen a sign of mice since. my car is finally safe."
"took longer than expected before the roaches in the basement stopped showing up. i was close to returning. then around day 11, my husband pointed out he hadnt seen a single one scatter on the workbench in days. 4 stars cause the initial wait was genuinely stressful, but it does work"
"retired last year. started spending more time at home and noticed spider webs along the window sills and corners every afternoon, something id been ignoring for years while still working. bought 5 units at my daughter's recommendation. by day 11 i stopped finding new webs. house feels like my own again honestly."
"found a big spider crawling across my 6 month olds NURSERY floor, then two more in the closet. i cannot adequately describe the panic i felt. ordered the 5 pack overnight shipping. plugged everything in that afternoon while still half-crying. didnt see another one after the first night. 2 months in, nursery is spotless. god bless whoever made this"
"we live on 4 acres that border cornfields. every fall we get FLOODED w/ field mice coming into the garage + basement. tried the 10 pack last yr, 3 in the garage, 2 basement, 5 in the main house. this season was the quietest in 20 years. worth every dollar, seriously"
"one unit was NOT enough for my 2200 sq ft home. i knew that was the risk going in but wanted to test before committing. after week 2 the ant trail had barely changed. ordered the 5-pack and placed them properly. within 10 days of full coverage no more trails anywhere. lesson learned: dont undercover ur house"
"bought our first house in march, by june we were finding roaches in the kitchen every morning when we came down. called 2 exterminators, BOTH quoted $450+ for the first visit PLUS a monthly contract. insane. ordered the 5 pack instead on a friends recommendation. saved $400 and they stopped showing up in about 11 days. new homeowner lesson"
"three cats. i am NOT using snap traps or poison with them around. period. saw my youngest cat staring intently at a gap behind the stove for like 3 days straight and then found mouse droppings, so something was obv there. plugged in PestRx, cat stopped staring by day 8. my cats dont seem to react to the devices at all btw."
"workshop in my garage where i restore vintage motorcycles. mice were gnawing the wiring harness on a project bike, absolute nightmare. installed 2 units in the garage. a week later, no new droppings or gnaw marks. been 6 months now, still clear. saved me from having to rewire an entire bike from scratch."
"Split-level home in upstate New York. Heard mice skittering in the upstairs ceiling that turned out to be over the hallway. One unit in the upstairs hallway, one on the main floor, one in the basement. By day 9 the ceiling was silent. Six months later, still silent."
"i wfh. spent a whole WEEK ignoring the odd spider by my desk until i found webs strung behind my monitor and one dropped onto my keyboard. cannot focus when something is crawling across your keyboard lol. plugged in 2 units, one in the office and one in the garage next to it. didnt see another spider after the next morning. back to productive."
"We spend winters in Florida and come back to Michigan in April. Last year we came home to ant trails in three rooms and the kitchen was a disaster. This year I left a 5-pack plugged in all winter. No trails, no nests, nothing. The house smelled like it did when we left."
"My Labrador kept sniffing and pawing at the baseboard behind the couch, he would not leave it alone. Found a small gap with mouse droppings right by it. Plugged in 3 units. Within 11 days my dog stopped going over there. Whatever was there left. Dog hasn't reacted to the devices at all."
"Cook professionally, spend most of my time in my home kitchen. Found a single roach behind the espresso machine one night and refused to accept it. No poison, no gel bait near food. Four units on the main floor, kitchen, pantry, mudroom, laundry. Eleven days clean and counting. My kitchen is sacred."
"Two things to know: 1) yes, this works, bought the 10-pack, the mice stopped showing up in the attic after 11 days. 2) they'd already torn up my insulation before I bought this. Four stars because I wish I'd bought it a year earlier. No fault of the product."
"Four kids, homeschooled, home 24/7. The idea of putting out roach gel bait on the floor was a non-starter. Plugged in 5 units around the house the day we found roaches in the laundry room. Ten days later the kids were back to running around barefoot without me panicking. Best decision."
"Cabin on a lake in northern Wisconsin. Uninhabited 5 months a year and spiders always took over the place, webs in every corner. This is the first spring we came back to a clean cabin. No webs, no nests, no unpleasant surprise. The 3-pack covered our 900 sq ft cabin perfectly."
"Bought this for my 82-year-old mother who lives alone. She'd found a trail of ants in her pantry and was too overwhelmed to handle bait stations. I drove over, plugged in 3 units, showed her the green lights, and left. Ten days later she called to tell me she hadn't seen anything. She sleeps better now."
"Just finished a kitchen remodel and noticed ant trails under the new cabinets within a month. Apparently the contractors opened up gaps I didn't know about. The 5-pack helped a lot but I had to seal two specific gaps first before it really worked. Worth it, just don't skip the sealing step."
"Two days before Thanksgiving, my niece said 'there's a roach!' in front of 12 people in my kitchen. I cannot explain the mortification. Ordered the 5-pack same night, had them plugged in by the following Monday. Christmas dinner was flawless. Never again."
"Older 1950s home on a crawl space. Hadn't realized how many entry points those create until I found spiders and webs all through the hall closet. Put 2 units on the main floor and one in the closet where the webs were. About eleven days in, completely clear. Have since sealed the crawl space vents as a separate project."
"Active-duty Navy, we move every 3 years. This is our 4th house in 10 years and every one has had roaches. PestRx is the one thing I pack with me now. New duty station in Virginia, plugged in 3 units the day we moved in. Zero roaches in 8 months. Worth packing across the country."
"Townhome with shared walls. The unit two doors down got condemned briefly last year because of an infestation, I started hearing mice in the shared wall within weeks. Shared walls mean shared mouse highways. Plugged in 3 units immediately. Clean for 5 months. HOA should honestly be buying these for everyone."
"Apartment above a Thai restaurant in Brooklyn. The restaurant below had a roach problem that became my roach problem. Landlord did nothing. Bought 3 PestRx units and plugged them in along the baseboards. Haven't seen one in 3 months. The restaurant still has problems. Not mine anymore."
"Pulled down my Christmas decorations from the attic and opened a box of garland to find it full of spiders and webbing. That was three years of storage with no detection. Bought the 5-pack that weekend. Next time I went up there, clean boxes, no webs. This is the peace of mind I needed."
"I run a small licensed in-home daycare. Eight toddlers in my house daily. The day I found a roach under the toy bin, I nearly shut down for a week. Ordered the 5-pack on expedited shipping. Plugged in by the afternoon. Never saw another one. My license and my business are safe."
"Attached garage had a steady ant trail coming in along the wall where it meets the house. One PestRx in the garage alone didn't solve it; I needed to also seal the gap they were using to get in. After I sealed the gap AND kept the unit plugged in, no new activity. Four stars because the product alone wasn't enough for my specific situation."
"Stored family photos and keepsakes in plastic bins in the basement. Found spiders and webs all over the lids and in the corners down there. Could not stomach the idea of them getting into irreplaceable family memorabilia. Two PestRx units in the basement, zero activity within 10 days. Irreplaceable things stay irreplaceable."
"I teach piano from a home studio. Started noticing spiders and webs in the corners of my practice room during lessons, not a great first impression for new students. Bought 3 units, placed one in the studio. Spiders were gone within 11 days. My 7-year-old students have not noticed and that is the entire goal."
"Brought home a vintage dresser from an estate sale. A week later, a trail of ants leading out of the drawer. The dresser apparently came with stowaways. Plugged in PestRx in the bedroom where I put the dresser. Seven days later, no more evidence. Still have the dresser, no longer have the ants."
"Converted a detached garage into an ADU for my mother-in-law. Two weeks after she moved in she called to say she'd heard mice scratching in the walls at night. Got a 3-pack, one for the ADU and two for the main house. She hasn't heard anything in 10 weeks. Mother-in-law approval unlocked."
"We had a sump pump failure last spring, minor flooding in the basement. A month later I started finding ant trails, apparently carpenter ants are drawn to water-damaged wood. The 5-pack helped cut it off but it took longer than i expected, right around day 11. One star off because a fresh infestation in a damp basement is a tough test case. Product still works, just be patient."
"Roaches living in my attached garage. They were coming through the door into my house, kitchen is right off the garage. Put one unit facing the garage door, one facing the kitchen door, one in the kitchen itself. Clean in 11 days. The garage-to-kitchen interface was the problem and this addressed exactly that."




Not seeing a change by week three? Move a unit toward where the activity starts, or use the 30-day guarantee. No hard feelings, no hoops.
"reduced the spider and ant activity but didnt clear it completely. my 1920s farmhouse has more gap and crack access points than i realized going in. customer support was actually great, immediate on the refund, no hassle whatsoever. i think this works, just not as a standalone solution when youve got real structural issues like i do."
Patricia is right, and we should have caught this earlier. PestRx repels. It cannot block a structural gap that gives pests direct entry. For older homes with foundation cracks or deteriorated weatherstripping, sealing entry points first is necessary. Patricia shipped the units back and we refunded her right away. If she ever seals those gaps, we'll make it right at no charge. Marcus, HelloPest
"bought ONE unit for a 2400 sq ft two story house to deal with mice. didnt work. contacted support and they explained i needed AT MINIMUM 3 units for that square footage, thats on the product page but i totally missed it. they sent me a 2-pack at no extra charge to complete coverage. after that it worked exactly as described. my mistake honestly"
This one's on us. The coverage calculator is there to prevent exactly this situation, and we should do a better job surfacing it. Brian's right that one unit can't cover a full two-story home, ultrasonic frequencies don't pass through floors or walls. We made it right with a free 2-pack. Leaving this review up because undercovering is the #1 reason PestRx underperforms. HelloPest Support
The frequencies PestRx uses are inaudible to people, dogs, and cats, and they don't affect electronics, WiFi, or medical devices. (Fish and small caged pets are the one exception, noted below.)
Ultrasonic frequencies are inaudible to humans of all ages. No chemicals, no residue, nothing for little hands to touch.
Dogs and cats can't detect PestRx's operating frequency range. No chemicals, no residue, nothing for them to touch.
Fish, hamsters, gerbils, and other small caged pets may be sensitive to ultrasonic frequencies. Do not place PestRx in the same room as their habitat.
Runs on a completely different frequency from WiFi, Bluetooth, and baby monitors. Zero interference with your devices.
PestRx operates at 25–65 kHz, entirely above the hearing range of humans, dogs, and cats. Your household hears nothing. Rodents, roaches, spiders, and ants are sensitive to vibration and sound in this range. They pick it up through their legs, antennae, and (for rodents) hearing, and avoid the surfaces and rooms carrying it.

Mice come in from the cold. Ants march in with the spring. Spiders settle in for fall. Roaches stay active all year. Most homeowners buy a different product for each one. One PestRx, plugged in, covers the whole rotation.
Plug it in before the season turns. If it isn't earning its outlet, send it back within 30 days for a full refund.
PestRx is built for the everyday indoor pests that share your floors and walls: mice and rats, cockroaches, spiders, and ants, with help against other crawling insects like fleas and stink bugs. Each one is sensitive to vibration and sound in this range, mice through hearing, insects through their legs and antennae.
This is the most common objection we hear, and it's a completely fair one. Every $15–30 ultrasonic device on Amazon emits a fixed frequency. Pests are adaptive. Within a week they habituate to a constant signal and stop responding. It becomes background noise, like a refrigerator hum. PestRx uses an adaptive pattern sweep that varies its frequency pattern instead of holding one note, so it doesn't hand them a single fixed tone to tune out the way a $20 device does. We won't pretend pests can never adjust to anything, so give it 7 to 14 days and move a unit if a room isn't changing. But if you gave up on a plug-in repeller before, you gave up on fixed-frequency. Not on the technology itself.
It depends on your home's layout. Square footage matters less than where the entry points and food zones sit relative to each other. A multi-story house with a garage and finished basement needs different coverage than a 1-bedroom apartment, and a townhouse with shared walls needs different coverage than either. Take the 2-minute coverage quiz for a count built around your specific home.
Cheap fixed-frequency devices, yes. That's their main failure mode: a single steady tone becomes background noise within a week or two and pests stop reacting. PestRx varies its pattern instead of holding one note, which helps it keep working longer. We won't claim pests can never adjust to anything. What we'll say honestly: give it the first 7 to 14 days, move a unit if one particular room isn't changing, and the 30-day guarantee is there if it doesn't work for you.
No. PestRx works on sound, not radio. It emits high-frequency sound waves in the 25–65 kHz range, a completely different thing from the radio signals that WiFi, Bluetooth, and devices like pacemakers use. It plugs into a standard 120V outlet and runs passively. There's nothing for it to interfere with.
Yes, for ongoing protection. Once the current pests clear out, new ones can move in, especially as the seasons turn. Keeping PestRx plugged in year-round creates a continuous barrier. No refills, no resprays, no maintenance. One device, plugged in, doing the job of the cabinet full of products you replaced.
It deters. It doesn't kill. Pests go where life is easiest. PestRx makes your home the harder, less comfortable option, so they move on. The ones already inside feel the field and head back out to easier territory. New ones read your home as occupied before they ever settle in. Killing the one bug you can see doesn't fix anything when more keep coming. Making your whole home a place they avoid does. No dead pests to clean up. No bait residue near your kids or pets.
Be honest with yourself here. If something is already nesting deep in your structure (a carpenter ant colony in damp framing, rats breeding in a wall cavity, rustling or scratching inside the walls), that's a job for a licensed pest professional to locate and treat at the source. PestRx is built to deter and prevent. It keeps new pests from moving in, and pushes out the ones passing through your living space. Once something has nested inside the framing, a plug-in is downstream of the real problem. We'd rather tell you that than take your money.
Yes for garages, unfinished basements, and attics with a standard 120V outlet, and that's often where the problem starts. Rodents and insects slip in through garage-door seals, crawl-space gaps, and utility penetrations before they reach your living space. Outdoors: PestRx is built for indoor use and isn't weather-rated for direct rain. Covered porches, screened enclosures, and weatherproof shed outlets work. For perimeter coverage, a unit on the nearest interior wall still works the adjacent exterior surface.
We'd rather give you an honest answer than oversell. PestRx works best as continuous, whole-home deterrence for light-to-moderate problems. For severe situations, a colony nesting in the framing, a heavy rodent infestation, or pests streaming in from one open entry point, PestRx alone isn't the full fix. In those cases, seal the entry point first, address any moisture or food source, then run PestRx as continuous prevention. Use the 30-day guarantee window to confirm it's working. If it doesn't, we'll refund you.
If PestRx doesn't do what we say, or if you're unsatisfied for any reason, ship it back within 30 days and we'll refund you in full. No hoops. No negotiation. No "store credit only."
We've processed 847 returns. Average time from receiving your return to refund: 2.1 business days.
Most homes end up with a cabinet full of single-pest products: one for mice, one for roaches, one for spiders, one for ants, and another for whatever turns up next. PestRx runs an ultrasonic range that the pests which feel their way along your floors, walls, and baseboards tend to avoid, so one plug-in does the work of a whole shelf. One device. No extra purchase.
Rodents hear ultrasonic sound natively, and the 25,000–65,000 Hz range sits in the band they find stressful, so they avoid the rooms where it's running.
Sense substrate vibration through cercal receptors at the rear of their abdomen. The signal reads like predator activity, so they leave the cabinets and wall voids they hide in.
They sense vibration through their legs, the same sense they use to hunt. It throws that off, so they stop setting up in your corners and move on.
Foragers pick up the signal and redirect to easier food outside, so new scouts never lay a trail into your kitchen to begin with.
Fleas, stink bugs, and other crawling insects that feel their way along the same floors and baseboards tend to avoid the field too.
Same plug, same 30-day money-back guarantee. No second purchase to cover the rest of the house.
They stopped buying a new product for every pest and plugged in PestRx instead. No more reaching for a new spray, trap, or exterminator every few weeks. Plug it in, and you're done thinking about it.
